Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!

I’ve been getting these random crashes since Monday. I didn’t have any last week.
I’m playing on a pc with steam.

Have you sent the crash report mention in the message to the devs? It should list in there what the cause is.
